stubburn shock on Santa Cruz Blur wont budge
G'day people, I trust you are all having a splendid weekend.
I'm trying to take off my 5th Element shock from my Santa Cruz Blur (Classic)... replacing it with the Fox rp2.
I followed the instructions as advised on SC:
https://www.santacruzbicycles.com/tech/blur_bearing.php
I successfully took out the top bolt (step 2), but when I repeat the practice on the rear shock axle (step 3) the unit wont budge, not even a mm and I'm swinging the hammer as hard as I dare. Now, I've removed both bolts from both sides of the axle and replaced one of the bolts without the cap, but it doesn't matter which side I try and displodge the axle it isn't shifting. Can anyone please suggest what else I need to do, short of growing some balls and swinging the hammer with a little bit more gusto!!
Thanks in advance.

I take it you've already hit the pivot with WD40...
Are you supporting it on the other side with the frame flat on the floor? That could make all the difference.

You using a dead-blow hammer? With seized parts it's sometimes better to switch to something with a steel head. You may have to replace the bolt afterwards as the head may be squished.

no. I tend not to introduce wd40 around my bike unless I really have to... sounds like that's where we heading! I'll hold off until other suggestions, or last resort ;-)
Yes, although I think there is room for improvement, thanks.

Nice idea. I'm just using an average joe's claw hammer, not sure what you would call it. But it doesn't pack the punch as you have described with a dead-blow hammer. I'll let you know how I get on when I find one.

No, no. A dead-blow hammer is a soft-faced one like they're using in the diagrams on the page you linked to. If you're already using a steel hammer then there's not much more you can do besides swing it harder, or find an arbor press to use instead.

OKay, it's moving... I gotta a buddy to help me who works in a bike shop. However the axle is still very stiff and appears bent. Given the gusto he was using to hit this thing, it budged about 1cm and I'll finish it off tomorrow. I had to stop for the evening as not to wake up the kids!
I guess I'm gonna need a new axle to boot. Damn!!

If the axle's bent, that's a pretty good indicator your shock has been bottoming out hard. You should buy a heavier spring along with that axle. Maybe get someone to check the amount of sag and make sure the damping is working OK too.

thanks again for the advice. i'll let you know how I get on. incidentally the hole through the shock bushings at the top of the shock are too small to fit on my bike. i'm on the hunt for the right fitting ot machine down the bushings i have to work with.
